-## board info:
+# STM32F40x 板级支持包
- STM32F4 discovery
- http://www.st.com/internet/evalboard/product/252419.jsp
+## 1. 简介
-## note:
+STM32F40x 是由意法半导体推出的Cortex-M4内核的高性能单片机
+包括如下硬件特性:
-in drivers/stm32f4xx_conf.h
+| 硬件 | 描述 |
+| -- | -- |
+|芯片型号| STM32F40x全系列 |
+|CPU| Cortex-M4 |
+|主频| 84MHz-208MHz |
-```c
- /* Redefine the HSE value; it's equal to 8 MHz on the STM32F4-DISCOVERY Kit */
- efine HSE_VALUE ((uint32_t)8000000)
+## 2. 编译说明
+
+
+| 环境 | 说明 |
+| ------------ | ------------------------------------------------------------ |
+| PC操作系统 | Linux/MacOS/Windows |
+| 编译器 | arm-none-eabi-gcc version 6.3.1 20170620 (release)/armcc/iar |
+| 构建工具 | scons/mdk5/iar |
+| 依赖软件环境 | Env工具/(MDK或IAR或arm-none-eabi-gcc)/git/调试器驱动 |
+
+1) 下载源码
+
+```bash
+ git clone https://github.com/RT-Thread/rt-thread.git
+```
+
+2) 配置工程并准备env
+
+(Linux/Mac)
+
+```bash
+ cd rt-thread/bsp/stm32f40x
+ scons --menuconfig
+ source ~/.env/env.sh
+ pkgs --upgrade
+```
+
+(Windows)
+
+>在[RT-Thread官网][1]下载ENV工具包
+
+3) 配置芯片型号
+
+(Linux/Mac)
+
+```bash
+ scons --menuconfig
+```
+
+(Windows(ENV环境中))
+
+```bash
+ menuconfig
+```
+
+在menuconfig页面配置并选择对应的芯片型号,若开发环境为MDK/IAR,则需要生成工程
+
+4) 生成工程(Mac/Linux下请跳过此步骤)
+
+(Windows IAR)
+
+```bash
+ SET RTT_CC=iar
+ scons --target=iar -s
```
-
- **================= IAR WARNING =================**
-
-After use `scons --target=iar -s` command to product IAR project, you have to add iar link file manually.
-IAR IDE steps:
-1. Project-->Options-->Linker
-2. Config-->Linker Configuration file
-3. select `Override Default`, then select `bsp/stm32f40x/stm32f40x_flash.icf`
-4. rebuild project
+(Windows MDK5)
+
+```bash
+ scons --target=mdk5 -s
+```
+
+(Windows MDK4)
+
+```bash
+ scons --target=mdk4 -s
+```
+
+5) 编译
+
+使用MDK或IAR请参见对应教程
+
+(Windows arm-none-eabi-gcc)
+使用以下指令设置gcc路径
+
+```bash
+ SET RTT_EXEC_PATH=[GCC路径]
+```
+
+(Linux/Mac arm-none-eabi-gcc)
+使用以下指令设置gcc路径
+
+```bash
+ export RTT_EXEC_PATH=[GCC路径]
+```
+
+编译(WindowsLinux/Mac arm-none-eabi-gcc)
+
+```bash
+ scons -j4
+```
+
+出现下列信息即为编译成功
+
+```bash
+ LINK rtthread-stm32f4xx.elf
+ arm-none-eabi-objcopy -O binary rtthread-stm32f4xx.elf rtthread.bin
+ arm-none-eabi-size rtthread-stm32f4xx.elf
+ text data bss dec hex filename
+ 41596 356 1456 43408 a990 rtthread-stm32f4xx.elf
+ scons: done building targets.
+```
+
+
+如果编译正确无误,会产生rtthread-stm23f4xx.elf、rtthread.bin文件。其中rtthread.bin为二进制固件
+
+## 3. 烧写及执行
+
+烧写可以使用仿真器 ISP等多种方式 此处不再赘述
+
+### 3.1 运行结果
+
+如果编译 & 烧写无误,会在串口2*上看到RT-Thread的启动logo信息:
+
+```bash
+ \ | /
+- RT - Thread Operating System
+ / | \ 3.0.4 build May 15 2018
+ 2006 - 2018 Copyright by rt-thread team
+msh />
+```
+
+*默认串口
+
+
+## 4. 驱动支持情况及计划
+
+| 驱动 | 支持情况 | 备注 |
+| ------- | :------: | :-----------: |
+| UART | 支持 | UART1/2/3/4/5 |
+| GPIO | 支持 | / |
+| hwtimer | 支持 | / |
+| RTC | 支持 | / |
+| eth | 支持 | LAN8720A |
+
+### 4.1 IO在板级支持包中的映射情况
+
+| IO号 | 板级包中的定义 |
+| -- | -- |
+| PB6 | USART1 TX |
+| PB7 | USART1 RX |
+| PA2 | USART2 TX |
+| PA3 | USART2 RX |
+| PD8 | USART3 TX |
+| PD9 | USART3 RX |
+| PC10 | UART4 TX |
+| PC11 | UART4 RX |
+| PC12 | UART5 TX |
+| PD2 | UART5 RX |
+
+## 5. menuconfig Bsp菜单详解
+
+| 选项 | 解释 |
+| -- | -- |
+| Enable UART1 (PB6/7) | 开启串口1,串口1的设备名为"uart1" |
+| Enable UART2 (PA2/3) | 开启串口2,串口1的设备名为"uart2" |
+| Enable UART3 (PD8/9) | 开启串口3,串口1的设备名为"uart3" |
+| Enable UART4 (PC10/11) | 开启串口4,串口1的设备名为"uart4" |
+| Enable UART5 (PC12/PD2) | 开启串口5,串口1的设备名为"uart5" |
+
+*部分选项需要在RT-Thread组件菜单中开启对应的设备框架才能显示。
